ILLIXR v4.0 Released

ILLIXR is proud to announce a new release: v4.0

This release of ILLIXR brings many new features and capabilities. There were a total of 16 pull requests merged which introduced 10 new plugins, overhauled several others, and addressed 13 issues. The new plugins include:

  - tcp_network_backend: a backend for Switchboard using TCP to transmit topics between two connected ILLIXR instances
  - offload_rendering_server: encodes OpenXR frames with FFMPEG and transmits them across the Switchboard network backend
  - offload_rendering_client: decodes frames transmitted from an offload_rendering_server instance and adds decoded frames to a buffer pool
  - openwarp_vk: an implementation of OpenWarp, 6-DoF asynchronous reprojection, in ILLIXR
  - lighthouse: uses libsurvive to connect with Valve Index lighthouses for head tracking
  - orb_slam3: and ORB_SLAM based plugin
  - hand_tracking: detects and reports the positions of joints and fingertips; if depth information is available, or distances can be calculated by parallax, the reported coordinates are real-world in millimeters, otherwise they are in pixel coordinates
  - zed.data_injection: reads in data from disk and publishes it as if it were the zed plugin, good for debugging and testing

Vulkan is now the default display back-end, and OpenGL is in the process of being deprecated from ILLIXR. See below for more detailed notes on the changes.
